930 cm
(b) 4v3 cm (c) 830 cm (d) 6 30 cm
non of its nnce is 88. The best​

Answer 1

Answer:

None of these

Step-by-step explanation:

Given, in a triangle ABC,

              a=8cm, b=11cm c= ?  

perimeter = 32 cm

      perimeter = a+b+c

          32 = 8 + 11 + c

          32  = 19 + c

            c = 13 cm

 

  s = (a+b+c) / 2 = 32/2 = 16

      Area = $\sqrt[s(s-a)(s-b)(s-c)}$  $\sqrt{s(s-a)(s-b)(s-c)}$

     Area = 8$\sqrt{30}$ cm²
